Abstract: A fan assembly for generating an air flow within a room includes an annular casing which defines an interior passage. The interior passage includes an air inlet, and houses, downstream from the air inlet, an impeller and a motor for driving the impeller to draw an air flow through the air inlet and into the fan assembly. The interior passage also has an air outlet from which at least a portion of the air flow is emitted from the fan assembly. The annular casing defines a bore about which the interior passage extends and through which a secondary air flow from outside the fan assembly is drawn by the air emitted from the air outlet.

Abstract: There is provided a method of controlling a direction of an airflow emitted from a fan assembly, the fan assembly being capable of changing the direction of the airflow emitted therefrom to any direction within a range of adjustment of the fan assembly. The method comprises receiving user inputs that select an angle of oscillation and that determine a central emission direction for the airflow emitted from the fan assembly, and controlling the emission direction of the fan assembly such that the emitted airflow oscillates through the selected angle of oscillation with the oscillation of the emitted airflow being centered at the central emission direction.
